I read this comprehensive review before purchase and you should too:http://www.imaging-resource.com/PRODS/canon-eos-m/canon-eos-mA.HTMI'm an amatuer photog for more than 40 years. Until recently, my only concession to digital photography was the purchase of inexpensive Canon point-n-shoots. As film photography has become a greater burden and digital has caught up in terms of quality while surpassing in convenience and affordability, my discovery of this little gem at a bargain price was perfect timing. Adding a $15 adapter, I can use may ancient but excellent FD mount Canon lenses - think F1 and AE-1 cameras. Auto-focus speed doesn't matter to me because I still prefer to manually set almost everything. That said, the AF performance of the EOS M seems equivalent to that of my son's Nikon 1.My purchases for my entry into serious digital photography to date include: the EOS M with Speedlite 90EX and EOS M 18-55mm IS lense: an SD card (PNY 64 GB High Speed SDXC Class 10): a spare battery (Opteka LP-E12 LPE12 2000mAh Battery Pack): a lense adapter (Fotasy Canon FD Lens to EOS M Lens); and a neck strap (OP/TECH USA System Connector Super Pro A).

I bought this for my Canon EFS 17-55 mm f/2.8 IS USM. I am still using it on the same lens and is doing a very good job without distorting or altering the images. Great stuff

If you want to use your old FD lenses, this is one of the best choices. All you need is an adapter ring "Fotasy Canon FD FL Lens to Canon EOS M". The pictures turn out great, you just have to get used to the manual adjustment but there is an automatic ISO adjustment to help, if you want.

This fit my 18-55mm EFS Canon lens just fine. Seems to do what its supposed to. Good price, fit, and quality.

Used this adapter with several different lenses of mine and a friends and it works perfectly with all of them. This adapter allows you to use EF or EFS lenses easily on the Canon RP.

Works as advertised. The elastic strap for the lens body tube fits both of my Canon Lenses, EFS 55-250mm and EFS 18-135mm. The adhering pad for the lens cap works best on the smooth surface edge where there is no logo underneath.

Works perfectly on my Canon T5i with the base EFS 18-55mm lens. Worked so well that I ordered another for the EFS 55-250mm lens I also have. No problems whatsoever with either lens.

I purchased a Canon FD to Leica M adapter in order to get some more use out of my 17mm Canon lens. I’m pretty impressed with it so far. It seems considerably better quality than the cheap imported adapters, and not as expensive as a Novoflex. The lens hooks up solid and it feels solid on the camera body. I will most likely try some of their other adapters as necessary.
